Pink's reaction to Christina Aguilera's AMAs Whitney tribute has the internet divided

The GIFable part of the internet has a (brief) new obsession.

Christina Aguilera took the stage at the American Music Awards to pay tribute to the late musical icon Whitney Houston. However, as the camera swooped in for the usual audience reaction shots, fans caught Pink with a rather perplexing look on her face.

A furrowed brow, and a slight shake of the head. Indicative of one of two things: either she was mildly repulsed by Aguilera's key fluctuations, or she was overwhelmed by her talent - and was really, emotionally feeling the groove.

As per usual, the internet had a lot to say on the matter. "Christina is really struggling with this Whitney tribute. Her vocals are usually spot-on. Those weird runs and her key fluctuations are best described by Pink's face (actual screenshot taken during Christina's performance)," one Twitter user critically wrote in reaction to the singer's performance.
